The main idea of recent fast ReID methods is the hashing algorithm, which learns compact binary codes and performs fast Hamming distance and counting sort. However, a very long code is needed for high accuracy (e.g. 2048), which compromises search speed. In this work, we introduce a new solution for fast ReID by formulating a novel Coarse-to-Fine (CtF) hashing code search strategy, which complementarily uses short and long codes, achieving both faster speed and better accuracy. It uses shorter codes to co","authors_text":"Guan'an Wang, Jian Cheng, Shaogang Gong, Zengguang Hou","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2020-08-16T03:02:49Z","title":"Faster Person Re-Identification"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2008.06826","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:6710ed7cf63c506595ef26e4a2884b942b0a7e4d1ae5fec3637ec0d8ee285635","target":"record","created_at":"2026-07-05T01:27:33Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"bfb8a5e5d81072fbe8103d09d7c8e14afee68cdc62fcfe6db9062d901a1b508f","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2020-08-16T03:02:49Z","title_canon_sha256":"e8a7f0523fcb6078100da445ba2532c924390b087c5f01300e1d1a444ee34e4f"},"schema_version":"1.0","source":{"id":"2008.06826","kind":"arxiv","version":1}},"canonical_sha256":"85d9446efc0ff69ec49f504806042ab7436e73703f87f33c5070940dc44e209f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"85d9446efc0ff69ec49f504806042ab7436e73703f87f33c5070940dc44e209f","first_computed_at":"2026-07-05T01:27:33.434088Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:27:33.434088Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"luubzmyA43xZc27zcZQ9tAuDCOmYFbd4xxapn7KPDEoDhFzYEnRHe0Wstfxcj/sidyNRD0In+VgFPMGyEgOQCg==","signature_status":"signed_v1","signed_at":"2026-07-05T01:27:33.434543Z","signed_message":"canonical_sha256_bytes"},"source_id":"2008.06826","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6710ed7cf63c506595ef26e4a2884b942b0a7e4d1ae5fec3637ec0d8ee285635","sha256:17c354d53af3434f425cb8d47e06f3d53a7e30ae4d3a25976016be17ca958909"],"state_sha256":"6785df9e26977c307652658d51685b1f6310e4bee44181f302138f66f553d9b9"}
